The hardware

  • 1 - status LCD display
  • 2 - 25 pin D-SUB inputs outputs
  • 3 - Ethernet (optional) not implemented yet
  • 4 - micro USB for upload firmware

Circuits

KIT assembly instructions

All components

Soldering in six steps

  • 1 - bottom pad J1 USB connector
  • 2 - U5 DIL socket
  • 3 - RL1 Relay
  • 4 - P1 P2 P10 P11 JP1 Pin header
  • 5 - S1 Reset button
  • 6 - J2 D-SUB connector

❏ Short JP5 JP6 SMD jumper padds on bottom side

Display

❏ Deploy from the left side Left LCD holder on PCB board

❏ Put LCD

❏ Deploy Right LCD holder on display and deploy to PCB from front side

❏ Display cabe - using only one same side of connectors

❏ Connect display and PCB board - Green collor shows polarity

Insert PCB with display to aluminium box and tighten with two screws

Power

❏ Connect power, typicaly 13,8V from transceiver

Configure output driver

We available two types of output drive

Open collector

Using for components with grounding outputs

  • Put in ULN2803A chip to U5 dil socket
  • Set two jumpers in P2 to LEFT side

Open emiter

Using for components controlled with positive voltage

  • Put in MIC2981 chip to U5 dil socket
  • Set two jumpers in P2 to RIGHT side
  • Connect power for output control to pin1 in J2 D-SUB connector| - this voltage use also for powered of band decoder and may be in range 8-24V

Configure outputs in firmware

  • Allways enabled.

An entrance band data, or frequency, converts to output band 0-14 which can be configured in the following table - Preset Band to output matrix - in default settings Band-1 corresponds to Output-1, etc. You can sets any combination outputs for each band separately. With change zeros and ones in the Matrix table. Band-0 reserved for out of range inputs measure.

Firmware

  1. Download and install last version Arduino IDE
  2. Download Band Decoder 2 firmware source from GitHub
  3. Preset two jumper in P10/P11 pin geader
  4. Connect micro USB cable between band decoder and PC
  5. Configure... (more in the chapter Configure TRX inputs)
  6. Select menu Tools/Board:"Arduino Nano"
  7. Select menu Tools/Port/YOUR-CONNECTED-PORT
  8. Upload firmware

Configure TRX inputs

First sets global frequency rules which they choose BAND number by frequency with a resolution of one Hz. Also may be use for partition one band to more subbands.

//Freq Hz from       to   Band number
     {1810000,   2000000},  // #1 [160m]
     {3500000,   3800000},  // #2  [80m]
     {7000000,   7200000},  // #3  [40m]
    {10100000,  10150000},  // #4  [30m]
    {14000000,  14350000},  // #5  [20m]
    {18068000,  18168000},  // #6  [17m]
    {21000000,  21450000},  // #7  [15m]
    {24890000,  24990000},  // #8  [12m]
    {28000000,  29700000},  // #9  [10m]
    {50000000,  52000000},  // #10  [6m]
   {144000000, 146000000},  // #11  [2m]
   {430000000, 440000000},  // #12  [70cm]
   {1240000000, 1300000000},  // #13  [23cm]
   {2300000000, 2450000000},  // #14  [13cm]
   {3300000000, 3500000000},  // #15  [9cm]
   {5650000000, 5850000000},  // #16  [6cm]

Second uncomment and activate only one input in source code

//=====[ Inputs ]=============================================================================================

Input Serial

Activate uncomment line

Not need any hardware settings, only send via USB to serial line ascii characters in preconfigured baudrate.

X,YYYYYYY\n

  • X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
  • YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.
  • \n - is LF Line Feed (0A in hex)
